To all whom it may concern:

Be it known that I, CHARLES ALGERNON Parsons residing. at Turbinia Works, Wallscnd-onyne, in the county ofv Northumberland, England, have invented certain new and useful Improvements in the Lubricat on of Sliding Couplings, of which the following is a specification.

The present invention relates to the lubrication of sliding couplings such, for instance, as are fitted in geared turbine mstallations to allow the necessary relative axial movement between a turbine rotor shaft and its pinion shaft.

The invention consists in the provisionof baflle plates so placed as to deflect the lubricating oil into the body of the sliding coupling-or to retain the lubricating oil in the body of the coupling. I

The invention also consists in baffle plates so arranged as to deflect the oil leaving the bearings into the body of the sliding coupling and retain the oil in the body of the couplingto the required depth.

The invention further consists in a sliding coupling having baflle plates for retainh ll In carrying the invention into efiect asillustrated in Fig. 1, two co-axial shafts a b are connected by a claw coupling com-' prising a hollow cylindrical central piece c adapted to' engage with claw members d e l on the ends of the two shafts,the central portion bein preferably surrounded by a casing f in w ich the adjacent end bearings g h of the shafts are formed.

Integral with the bearing adjacent to the coupling, circular or partly circular baflles t t are provided projecting toward the cou-' pling and adapted to deflect the oil leaving the shaft bearings into the body of the coupling.v There are also provided lend pieces Z Z adaptedto inclose the coupling and to prevent the-escape of oil from the central Specification of letters Patent.

cylindrical member, these end pieces being provided with outwardly projecting flanges m m which assist in directing the oil into? Patented May 13, 1919. 1 Application filed September 12, 1917. Serial no. 191,010.

In the form of the invention shown.v in

Thls insures a How of this modification also instead of the bafiles t t in one with the bearings, circular or partly circular bafile plates 7c is are fitted to the bearings so that they project toward the coupling. I

According to the form of the invention shown in Fig. 3, the circula ieces Icon the shaft bearings g deflecting t e oil from the bearing into the coupling are extended beyond the inner lip of the end pieces I which inclose the coupling.

In the above described modifications'of the invention, the oil supplied to the cou-' plmgs is that which escapes from the bearmgs.

In all the modifications of the invention above described, except those in which the pipes 10 arereplaced by holes in the central body 0, centrifugal action causes the oil to stand u to the level of the inner diameter of the endplates, or to .the level of the inner ends of-the pipes go, so that the clawsof the coupling are drowned, and at the same time have fresh oil circulating through t e Having now described my invention, what I claim as new and desire to secure by Letters Patent is 4 1. A slidin coupling comprising in com bination a ho low cylindrical central piece, claw members adaptedto be connected to the shafts to be coupled, means on said central piece adapted to engage with said claw duct oil from the hearings to the interior of said centralpiece, as set forth.

2. A slidin coupling comprising in combinhtion' a ho low cylindrical central piece,

7 10s members and bafileplates adapted to conclaw'members adapted to be connected to the shafts to be coupled, means on said central piece adapted to engage with said claw members, baflfle plates extending inward radially and then outwardly attached to said central piece, and baflie plates adapted to conduct oil from the bearings to the interior of said central piece, as set forth.

3. A sliding coupling comprising in combination a hollow cylindrical central piece, claw members adapted to be connected to the shafts to be coupled, means on said central piece adapted to engage with said claw members, a casing surrounding said central iece, said casing carrying bearings for the shaft,

' and baffle plates adapted to conduct oil from the hearings to the interior of said central piece, as set forth.

4. A sliding coupling comprising in com bination a hollow cylindrical central piece, claw members adapted to be connected to the shafts to be coupled, means on said central piece adapted to engage with said claw members, inwardly rojecting pipes open at their inner ends and adapted to carry oil oil beyond a certain level from said central piece, and baffle plates adapted to conduct oil from the hearings to the interior of said central piece, as set forth.

In testimony whereof I have afiixed my signature.

CHARLES ALGERNON PARSONS.
